CLAY-DISINTEGRATOR.

SPECIFICATION-forming part of Letters Patent No. 322,393, dated July 14, 1885.

Application filed April 25, 1885. (No model.)

To all whom it may concern.-

Be it known that we, CLAYTON POTTS and ALBERT Po'r'rs, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana,'have invented a new and useful Improvement in Olay-Disintegrators, of which the following is a specification.

Our invention relates to an improved machine for finely dividing and tempering clay.

The object of our improvement is to disintegrate the clay by means of a revolving cylinder, which shall remove successive portions from a mass of clay which is automatically pressed against the cylinder, as hereinafter fully described.

The accompanying drawings illustrate our invention.

Figure 1 is a side elevation. Fig. 2 is an elevation showing the opposite side. Fig. 3 is a plan. Fig. 4. is a vertical section at a, Fig. 3.

A is a cylinder mounted on a shaft, b, having suitable bearings on the frame B. Said cylinder is of such length as to nearly fill the space between the sides of the frame. A series of steel bars, 0 c, are fitted into longitudinal grooves in the periphery of the cylinder, where they are secured by flush screws at each end, or other suitable means, whereby they are adjusted so as to present a sharp corner, (1, Fig.

- 1,projecting above the surface of the cylinder. ,.Opposite cylinder A a strong plate, D, is

mounted on a shaft, 6, so as to swing in bearings on the frame B. The central part, f, of said plate is cylindrical in outline, the upper portion, 9, presents a straight surface, and the lower portion, h, presents to the cylinder a curved surface corresponding to the periphery of the cylinder. Plate D is caused to oscillate in its bearings by means of an eccentric wheel, 1', on a shaft, j, mounted in suitable bearings on the frame, and connected by a yoke, 70, with an arm, I, secured to shaft 6. Motion is given to shaft I) by a belt running over driving-pulley m, and shaft j is revolved by means of friction-gearing, consisting of a wheel, at, secured to shaft b, a wheel, 0, secured to shaft j, and an intermediate wheel, 11, mounted on ashort shaft having bearings in a swinging adjustable frame, 4*. The opposed sides of cylinderA and the upper and central portions of Plate D form, together with sheet-metal end swinging plate,

plates, 8 s, which are secured to the frame, a trough, one side of which approaches and. recedes from the other at intervals, and which has at the bottom a narrow opening, it, of constant width.

The operation of our machine is as follows: Plate D being swung back to the position shown in dotted lines Fig. 4, the moist,

untempered clay is thrown into the trough above mentioned. Cylinder A, revolving rapidly, successive portions are removed from the mass of clay and carried through the opening it by the scraping-bars c, at the same time the upper portion of the plate D moves slowly toward thecylinder, thus keeping the mass of clay in close contact with the cylinder as successive portions are removed. The force with which plate D is removed toward the cylinder is regulated by drawing the intermediate friction-wheel, p, more or less closely in contact with the wheels n and o by means of the screw-nut u, thus lengthening or shortening the frame 1', the purpose being to cause enough friction between the wheels to move plate D sufliciently to keep -the clay in contact with the cylinder, and also to slip when necessary to prevent undue pressure against the cylinder. The finely-divided clay, after passing through opening t, falls upon the lower curved portion of plate D, and from thence to the incline w. If the clay is quite moist, some of it will adhere to the curved portionof the plate, and y a suitable angle, as that shown in dotted lines,

Fig. 4, or any intermediate angle between that and the position shown in full lines, so that the mass is fed to the cylinder by force of gravitation alone.

We claim as our invention--- 1. In a clay-disintegrator, a supportingframe, a cylinder arranged to revolve, and a both mounted in said frame,

' as specified.

3. In a elay-disintegrator, a supportingframe, a cylinder arranged to revolve, and having scra1')ing-bars attached to its periphery, and an inclined plate, both mounted in said frame, and forming opposite sides of a trough for the reception of clay, all combined substantially as specified.

4. In a clay-disintegrator, the combination, with the revolving cylinder, of the swinging plate consisting of a central cylindrical portion, an upper straight portion, and a lower curved portion, all substantially as specified.

5. The combination, with the supportingframe, the revolving cylinder, and the swinging plate,of the shaft j, eccentric i, yoke 70, arm I, and wheels 02, 0, and 19, substantially as and for the purpose specified.

6. I11 a clay-disintegrator, the combination,

with cylinder A, having a series of longitudi-r nal grooves, of the scraping-bars c, adjustably secured in said grooves, for the purpose specified.
